Marktronic PortaDot 50-25
Whenever workpieces are too heavy, too large or too unwieldy to be brought to the marking machine, the PortaDot 50-25 portable dot peen marker comes into play. It has been specially developed for mobile applications and offers a combination of lightweight construction, high precision and programmable marking technology that is unique in this class.
Weighing only 2.3 kg, the PortaDot 50-25 is one of the lightest professional dot markers on the market – yet it delivers the same uncompromising performance as large stationary marking systems. This makes the device ideal for flexible use directly on the workpiece, whether in production, service, maintenance or in areas that are difficult to access.
Your advantages – compact, powerful and mobile
The PortaDot 50-25 offers a host of advantages that make both mobile and stationary use a real efficiency gain:
- Lightweight design – only 2.3 kg, making it particularly easy to handle

- Highly flexible – versatile use in almost all industrial sectors
- User-friendly – ergonomic design & intuitive software
- Quiet, fast and powerful – ideal for production environments
- Wide range of applications – from steel processing to serial marking
- Intelligent marking solutions – 2D codes, serial numbers, time/date and much more
- Optional battery operation – perfect mobility without cables
Typical areas of application
The PortaDot 50-25 portable dot peen marker is suitable for almost any marking requirement – from simple component marking to complex industrial applications:
- 2D data matrix marking
- Marking of bearing housings and steel components
- Chassis and vehicle components
- Cast and forged parts
- Programmable serial marking
- Component identification and traceability
- Localisation of workpieces
- Serial numbering
- Time and date markings
- Batch and lot marking
- Marking of part numbers
This makes the device perfect for manufacturers, suppliers, maintenance personnel, workshops and companies with high requirements for traceability, quality assurance and documentation.
Lightweight and ergonomic – for fatigue-free working
With its particularly low weight of 2.3 kg, the PortaDot 50-25 enables fatigue-free working, even during longer periods of use.
A patented aluminium marking head, protected by a durable plastic housing, ensures stability and durability. This allows you to mark heavy components directly on site – without additional transport and without wasting time.
High marking performance and maximum precision
The marking area of 50 × 25 mm covers most mobile marking applications completely.
The variably adjustable embossing force enables optimum marking depth on almost all materials up to 62 HRC (800 HV).
The spindle-driven marking head also ensures exceptional precision – an important feature for:
- Easily legible component labelling
- precise 2D data matrix codes
- deep and permanent dot markings
Easy to use – ready for immediate use
The ergonomic design, clear controls and powerful software ensure that the PortaDot 50-25 is ready for use immediately after switching on. Operation is intuitive and allows:
- Selection of different fonts and font sizes
- Marking at angles or in curves
- Serial numbers, time and date codes
- Saving recurring layouts
- Quick text changes via keyboard
The Windows software (optional) allows additional control via a familiar PC interface – ideal for companies with network integration or centralised data management.
Quiet, fast and efficient marking
As the device does not require compressed air and is powered exclusively by an electrical connection, it is significantly quieter than pneumatic marking systems. At the same time, it impresses with its high marking speed and particularly efficient operation.
Hardware options for maximum flexibility
A wide range of accessories is available for different applications:
- Prism attachments for round components
- Table and column stands for stationary applications
- Connection cables up to 9 m (3 m standard)
- Windows software for network and storage applications
On request, we manufacture customised fixtures and material holders.
